The calibration process of the current visual inspection apparatus generally occurs at the site of use, i.e., the calibration and installation of the visual inspection apparatus is performed directly at the site of use when the visual inspection apparatus is required to be used. However, because the professional ability of the installer is different and the field conditions of the installation site are different, the efficiency of the configuration process in the installation process is low and the accuracy of the configured visual inspection device is poor.
In order to solve the above technical problems, please refer to fig. 1, fig. 1 is a schematic structural diagram of a calibration device of a visual inspection apparatus and a visual inspection apparatus provided in a first embodiment of the present application, the first embodiment of the present application provides a calibration device of a visual inspection apparatus, which is used for calibrating the visual inspection apparatus, as shown in fig. 1, the visual inspection apparatus includes a camera module 300 and a light source module 400, as shown in fig. 1, the calibration device of the visual inspection apparatus includes: the distance adjusting assembly 100 and the upper computer 200, the distance adjusting assembly 100 is used for adjusting the distance parameter between the camera module 300 and the light source module 400, and the upper computer 200 is used for controlling the camera module 300 and the light source module 400 to adjust the parameter. In addition, the upper computer 200 is further configured to output a calibration document, where the calibration document includes a parameter of the camera module 300, a parameter of the light source module 400, and a distance parameter between the camera module 300 and the light source module 400 when an image captured by the camera module 300 meets a calibration standard.
